It turns out the API I used was an undocumented one, Google got upset, and I had to close down the site.
If I find a way, I might get it back online one of these days.
Thanks to all who used and supported the site.

Clicktrotter was a site that produced a random photo from around the world every time you clicked your mouse button.
You could vote for the photos, go through your past votes, and check a simple top list.
